This invention relates tOdeVces for supplying lubricating oil to thevvarious bearings or journals of a machine. Y I

p An object of the invention is to provide 5 improved means `for delivering` lubricating oil at various rates to the dilferentjournals..

of a machine, and whereby the ratefof delivery may be definitely' predetermined to meet the exact requirements for each'loearing.v

m A. `further object of the invention is to provide an improved device of thisv character wherein lubricating oil may be supplied from a central single container either by gravity feed or pressure feed, at diif'erentrates toa l5 plurality of conduits, each leading vto a separate bearing. y v

The objects of the invention are accomplishedA by `a construction ask shown in the drawings, wherein: i

With the arrangement above described upon each upward stroke of cross head 16, the pockets 18 of the sleeves or oil measuring devices 17 lift different delinite quantities of oil to the inlets of the different conduits 5 acby gravity through the conduits 5 and conduit connections 9 therewith to the different parts of the machine which is to be lubricated. Y p

In ca'segravity feed cannot be relied upon, thecro'ss head 16, as shown in Figs. 7 and 8 carries posts 22 supporting a bar 23 from whichdepend plungers 24 which it and enter'the Vtubes 57011 thedown stroke? of the plunger, and force the oil inthe conduits 5 past a check valve 25 shown in the lower Vend thereof. Y wln order to modify the delivery of oil of all the carriers, an adjusting means 26 is providedv for regulating the upward stroke of piston 14. This means is shown as a thumb screw threaded into the cap'` of'fcylinder 12 and affords a fine adjustment so that the Vlimit of upward movement of the oil carriers l17 may be exactly regulated as desired.

In the operation of this lubricator, the oil level in the container 1 is maintainedby any desired meanssuch as automatic float controlled'feed thereto. The manner of recipro- 'eating the'crossfhead V16 is also Vnot essential to this invention, as various appliances are suitable for suchy purpose. i 'Y It is intended that it` be reciprocated either thedelivery of onlyy the required amount of 'oil' to each of the conduits leading to the bearingsof the'machine lwhich is Vto be lubricated. .f The'measuring devices 17 having different foil carrying capacities will, upon each reciprocation, deliver different quantities of lubrianoil conduit extending upwardly therein, Y

and having an inlet for oil above the normal oil level, an oil carrier slidable along said conduitv for carrying oil upwardly to the conduit inlet, means for reciprocating said oil carrier, and a plunger movable with said oil Vcarrier and iitting within said conduit for Vforcingthe delivered oil through the concording to the oil carrying capacity of-theV pockets 18. The delivered oil may then flow duit.

2. ,A lubricator comprising an oil supply container, said container being provided with an oil conduit extending upwardly therein, and having an inlet for oil above the normal oil level, an oil carrier slidable along said conduit for carrying oil upwardly to the conduit inlet, means for reciprocating said oil carrier, a plunger movable with said oil carrier'and fitting within said conduit for forcing the delivered oil through the conduit, and means for preventing backward flow of'oil through said conduit.

3. A lubricator comprisingva supply container, 'a plurality of tubes mounted within saidv Vcontainer and extending vertically therein s'o that their upper ends extend above lthe oil in said container, inlet openings at the upperends ,of said tubes, oil carrying tubes communicating with the lower ends of said. tubes, sleevesv slidably mounted upon saidY tubes, said sleeves being provided with oil carrying pockets means for reciprocating said sleeves along said'tubes whereby oil in the pocketsV of said sleeves will be delivered to the inlet openings at the upper ends of said tubes, said means comprising a carrying member for said sleeves, and means attached to said carrying member for lifting and lowering it at regular intervals.

cant to the conduits 5; When .at the upper j ends of theirstroke, the oil drains from these carriers into the open ends of conduits 5 and Afiows by gravity from these conduits into the :conduits 9 and into the machine bearings. In

casesjwhere gravity feed is not ,convenient for any'particular bearing, the delivery of the oil isrinsured by means Vof the plungers 24 V which serve to force it through the conduits.
